From c887470e0e3310c81ecdb7e736bc5d2ead45db2a Mon Sep 17 00:00:00 2001
From: Ivan Maidanski <ivmai@mail.ru>
Date: Mon, 6 Apr 2015 20:06:47 +0300
Subject: [PATCH 1/1] Do not include sigcontext.h and asm/sigcontext.h (these
Linux headers define sigcontext which is no longer used as replaced with
ucontext_t in GC 7.0alpha1)
* os_dep.c: Do not include linux/version.h (do not test
LINUX_VERSION_CODE), asm/signal.h, sigcontext.h, asm/sigcontext.h
since struct sigcontext not used in GC v7+.
